OK, so how big is our bird predation problem? Did I get an answer to my question from last night?

Probably. But first a few related items that multiple people pointed out in comments. First, habitat destruction is a way bigger problem than cats, so if you want to worry about the fate of North American birds, that’s #1 on your list. Second, overall numbers are only part of the story. Even if cats aren’t responsible for wholesale decimation of the bird population, they might still be responsible for serious damage to specific species in specific places. Third, although it’s true that it’s natural for cats to kill birds, the cat population in the United States is artificially high thanks to all of us cat lovers who keep them as pets. So the total amount of feline bird hunting is higher than it would be in a state of nature. There’s more in the comment thread if you’re interested.

Still: how many damn birds are there in the United States? John Trapp rounds up the literature here and figures the best guess is around 10 billion birds in spring and 20 billion in the fall. Meanwhile, the aptly named book, “How Many Birds Are There?” estimates 200-400 billion birds for the entire world, which is pretty consistent with 10-20 billion in the U.S.

So, assuming once again that cats really do kill 500 million birds a year, as the American Bird Conservancy claims, it means they kill something like 3% of the total bird population of the country. The error bars are probably fairly large on this number, but at least it provides the right ballpark. So now you know.

REAL QUICK, REAL URGENT

Minority rule, corruption, disinformation, attacks on those who dare tell the truth: There is a direct line from what's happening in Russia and Ukraine to what's happening here at home. And that's what MoJo's Monika Bauerlein writes about in "Their Fight Is Our Fight" to unpack the information war we find ourselves in and share a few examples to show why the power of independent, reader-supported journalism is such a threat to authoritarians.

Corrupt leaders the world over can (and will) try to shut down the truth, but when the truth has millions of people on its side, you can't keep it down for good. And there's no more powerful or urgent argument for your support of Mother Jones' journalism right now than that. We need to raise about $450,000 to hit our online fundraising budget in these next few months, so please read more from Monika and pitch in if you can.
